ROLLER-TABLE LINE SHAFT BEARING.

Application filed March 7, 1924. Serial No. 69?,496:

The present invention relates broadly to shaft bearings, and more. particularly to roller table line shaft bearings.

The purpose of the invention is to provide a mounting for the bearings of a power shaft which will permit the shaft to bereadily shifted laterally in order to disconnect it from the driven element or elements.

W The invention is particularly useful in connection with the line shaft 'of' a roller table for rolling mills and is so illustrated in the accompanying drawings, in which Figure 1 is a fragmentary plan view of a 4 portion of a roller table;

Figure 2 is a view similarto Figure 1, but showing certain of the parts 1n horizontal section, the section being taken on the l1ne II-II of Figure 3; v

29 Figure 3 is a-vertical section on the line I IIIII of Figure 2, and v Figure 4 is a' detail view of a filler block. In the illustrated embodiment, of the invention, 2 designates a table beam in which are journaled the necks 3 of rollers (not shown), these necks having the usual mitre J gears 4.- mounted thereon. Meshing with the mitre gears & are mitre gears 5 mounted upon the usual line or power shaft 6.

The line shaft is mounted in bearings supported by the table girder. Each bearing is divided horizontally to form a lower block 7 and an upper block 8, and the bearing rests upon a depressed seat 9. At one sideofthe bearing is a lateral wall 10, and at the opposite side a slotted lateral wall A filler block 12, shown in detail in Flgure 4, is placed between the bearing) and the slot-tedwall 11 and maintains the caring in engagement with the opposite lateral wall 10. The filler block is provided with flanges 13 at its opposite ends which engage vertical edges of the slotted wall 11 and prevent the.

filler block from moving longitudinally. of the line shaft. Thebearing is provided at its opposite ends with flanges 14 which engage vertical edges of the wall 10 and of the filler block and prevent the hearing from shifting longitudinally of the line shaft.

In order to hold the bearing upon its seat 9 and the filler block in position, a removahle clamp 15 is provided. This clamp bears at one end upon a ledge, 16 of the tablebeam, and atits other end bears upon the bearing through a half round 17 This shifting laterally by the walls 10 and 11.-

half round has its flat side in engagement with the upper bearing block 8 and 1s held in a recess in the clamp. The clamp is held in operative position by a single bolt 18 which is formed with an eye portion 19 at its lower end, through which a pivot pin 20, positioned below the seat 9, passes. This 'bolt extends vertically through a slot 21 in the filler block 12, and passes through an opening in the clamp. The upper end of the bolt is screw threaded and has nuts 22 mounted thereon. When these nuts are tightened, the bearing is held firmly on its seat and the filler block 12'can'not be removed, since the clamp extends over the same. The clamp is positioned between the flanges 14 of the upper bearing block 8, and y I is prevented from shifting longitudinally of the line shaft thereby. It is prevented from The portion of the clamp 15 which overlies the bearing is recessed to provide a chamber 23 for supplying lubricant to the journal portion of the line shaft. This chamber feeds the lubricant to said journal portionthrough anopening 24 extending I through the clamp, half round 17 and upper bearing block 8. y

With the line shaft mounted in the manner above described, if it is desired to remove a table roller the nuts 22 will be removed from the bolt 18 at each of the line shaft bearings, permitting the removal of the clamps 15 and filler blocks 12; The bolt 18 will then be swung through the slots 'of the walls 11 into the dotted line position shown in Figure 3. The line shaft 6 may I then be shifted away from the center line of the roller table b an amount equal to the thickness of the ller blocks 12. This is a s'uflici'ent movement to unmesh the line shaft mitre gearsfrom the roller mitre gears and permits'the removal of any table roller.

In order to protect each hearing from dust, scale. and the like, and same may be covered by a suitable hood 25 held in posi-. tion on the table girder and ada ted tobe removed by simply lifting it oft o the same.

.The advantages of the invention will be apparent/since it provides a mounting for the line shaft of a roller table which per mits the shaft to be shifted away from the center line of the table upon the removal of a relatively small number of parts. Therefore, when a roller burns out, it is possible no to disconnect the. drivin gear quickly and remove the burnt out rol er. Thls mounting for the line shaft also permits the shaft to be readily removed from or assembled with the roller table. While, as already pointed out, the invention is particularly useful in connection with the line shaft of a roller table, its use is notshaft= employed in the specification and claims is a term of description and not of limitation, and is intended to include broadly the journal portion of any rotatable element.

It will be understood, of course, that the invention is not limited to the exact details and arrangement-of parts shown, as many modifications may be made therein without departing from the s irit of the invention or scope of the appen ed claims.
